Default Anyone in Houston running Enginuity Open-Source Tuning?

Im about to buy my Tachtrix cable and download the Enginuity software but would feel more confident in what I was doing if I could see the stuff in person before I buy. Does anyone around town already run this program? How do you like it and are the shelf maps any decent?

I've been using it for a little over 3 months. I used a Stage2 map from osecuroms.org, and it worked ok. Nothing really wrong w/it, but my car wasn't as strong on it as w/the AP St2 map. I bought an XPT Stage2 map the same day, and my car liked it much better.

If you have any questions or need help, just let me know.

Paul, did you get yours set up?

with this method of flashing, is it still possible to "kill the ecu" after over 100 flashes?

Not to start an argument!

But what electronics schooling/knowledge do you have to make that statement?
How do you know this to be true ?

Well lets see, if I need to re flash my computer in my car up to 100 times, that would mean that I would have made 100 Different modifications to my car, or changed between maps for, street / drag / rally or any variation of driving . I think that the question should be, Is the Tactrix cable & EcuExplorer software and a $25.00 downloadable program the way that KnightWRX wants or needs to go ????

Like I said KnightWRX, I live near you and if you want to meet somewhere and check out the cable and software, I'll be glad to help you out.

either you or fathead would be great. Im running a stage zero Vishnu unichip map right now for the last 2 years. Im pretty sure I can do better with anything. I still need to get the cable to get started. Ive got the laptop already, Im just concerned if Ill be able to navigate the software easily. Dont want to mess anything up on the car learning it...haha.

Ill PM you both when Im ready....thanks guys.

Yes - this is a hardware limitation, not software. Our cars use custom control chips with embedded flash devices which are only rated by the manufacturer to 100 write/erase cycles. Look hard enough on the openecu.org website and you'll find the datasheets to confirm. You can always run more write/erase cycles on the chip, but the manufacturer of the chip will not guarantee operation.

I've been working with similar products since '96. Embedding a flash memory on a digital logic process results in memory with greatly different characteristics than standard flash devices.

Smoother, stronger in mid-range, very good overall.

My car hasn't seen a dyno, and I haven't been to the track since I put the XPT on, but my datalogs show more boost throughout the rev range in every gear. I think there is a thread in Engine Management & Tuning that has a dyno. Also, you might look there, as well as osecuroms.org, for reviews of the 02-03 maps.

I don't know if the Open-Source tuning is live tuning or not, but your statement can be a little misleading. As an example, ECUtek is not live tuning. Therefore, you do a pull, make changes to a map and reflash the ECU. One tuning session can be 10 flashes or more.

AFAIK Rancid is correct on this. Open source is not live, unless there has been a recent improvement I'm not aware of. If I want to make changes, I have to make them "off-line," save them, then flash the ECU again. I believe the same limitation exists for AP and Ecutek.

I don't want to discount the concern about "number of flashes", but I seem to remember reading a good number of tuners and self-tuners professing to flashing the same ECU well over 100 times. If I were ever to approach the 100-flashes mark, I would probably be more concerned about other issues (turbo lifespan, worn internals, dead tranny) than about the chip manufacturer's rating. In my view, the ECU is just one of several expensive parts we put on the table when we mod. I'd rather replace a turbo (more fun), but the headache and expense are equivalent in my mind.

So what your saying is, every time i press the defrost button to log a pull, I have just used up one of my 100 flashes!!!!!!

I Don't Think So.

Open source is not real-time tuning. Enginuity is working on it....

To my knowledge, there has never been a ecu to crash or malfunction due to too many flashes....

I'll get nhlurl to chime in in here.

Goddamnit you're stupid. Not logging. Loading a new map while tuning. Two totally different things.

Logging is grabbing the data the ECU reads so you can view it on your computer.

Lets say you log some data. Now you say "Golly, I need more timing!" So based on that log, you modify a map and then flash it onto the ECU. Now you log again. "Golly, now I need more fuel!" Based on the next log, you adjust the map, and reflash the ECU. Therefore, to make two adjustments to the map, you flashed the ECU twice. Of course, you could make both those adjustments at the same time and use only one flash, but if you didn't, it would take two flashes to make those changes.

In the first place Rancid, obviously taking God's name in vain doesn't bother you, it does me and I'm sure I am not the only one.

In the second place, you need to read my post that you quoted from, it says the same thing that you said.

In the third place, I'm not stupid.

stu·pid (stū'pĭd, styū'-) pronunciation
adj., -er, -est.

1. Slow to learn or understand; obtuse.
2. Tending to make poor decisions or careless mistakes.
3. Marked by a lack of intelligence or care; foolish or careless: a stupid mistake.
4. Dazed, stunned, or stupefied.
5. Pointless; worthless: a stupid job.

1. Everything offends somebody, so stop whining.

2. If you re-read your own post, it implied that you only changed your map one time after mods were made. If you read my post, it implies that you might only modify one part on your car, but modify the map several times for that single mod, and therefore reflash your ECU several times for one single mod.

3. You are stupid.

Stupid isn't the right word. It's overused and under-dramatic. You're what we call in the business a "fukktard".
